OBJECTIVES

• Students are introduced to the basic concepts of
  GPS, Plate Tectonics, and Earthquakes.
  
• Students will use several software packages for
  data analysis EXCEL, MATLAB, and JPLs DISLOC
  GPS/GIPSY programs.
  
• Students will apply their knowledge to analyze
  and model GPS data for earthquake displacements.
  
• Students learn about current GPS research
  project from guest speakers lecture series.
